You should also try connecting from another device which will determine if the problem lies with the specific computer.

2. Input Accurate VPN Server Credentials

The VPN name or address you provide must match the one assigned by the VPN provider. Check if the VPN service has changed the IP address of the server in case you have entered the old one. Changing of IP address is more common with DHCP networks.

The changes can be made through the broadband router you are using at home. If that doesn’t solve the problem then go for a firmware update for your router.

The above steps should solve the problem of VPN error 800. If not, then the VPN server may be offline or temporarily unavailable.
